wind noise

I love my truck, but have always complained about the wind noise. Now I get this annoying 'whistling' sound on windy days and @70/75 MPH, oe or more. Sounds like someone trying to learn to play the clarinet! We can't tell where it is coming from. Any suggestions?

This has been an aggravation of mine since I got my 08 Tacoma in Oct 07!! I traded a 10 year old Conversion Van that had a lot of wind noise and I figured I would get a new truck and get some peace and quiet, well I was wrong, the new one is as noisy as the old one.

The Access cab has a gap behind the back door panel to allow it to open and I believe this causes a vacuum and allows the weather seals to let in some (a Lot) wind noise.
